This invention krelates toVy apparatus for receive an end 21of a locking lever 22 which-fsu` locking an automobile and stopping the enc ispivotally .mounted as`at23to'the housing gine by asingle mot-ion` on the part of the of the .transmission gear, The notches in operator, this applicationbeing acontinua-v the shifter rods 13 and 14 are so positionedA 5 tion kof my co-pending applic-ation SerialiNo'. that when the vshifterfrod 13vis shifted for-` l 105,343, tiled April 29, 19,26 as to all subject ward, the notch 17 will be opposite the notch 55 matter common to both., An object of the in-, `20. vVVhenthi's, shifter rod is shifted yrearvention istolockmthecar in severalv` respects wardly, the locking end V21 of the lever 22,y so as to makeit exceedingly 'difficult for a will rest against the forward end ofthe rod,l l

io person not in possession of the p proper vkey 13 when it occupies the notch 2O in the rod 14,

to operate the'car. By my invention, all the In, likeunanner, vwhen the shifter rod 14 is 60 devices for locking various parts vare put into shifted, the notch 19 or the forward end ofthe operation by one act such as that of turning rod will cooperaterwith .the notch 18 to enable a key in its lock, Further advantageous fea the locking end 21 to lock both rods in any.

5 tures and combinations will be apparent to position of operation. A compression spring one skilled inthe art from the disclosures ofV 24 may be provided to press-the `lever 22565 my invention in the following description downwardly toward its locking position,yal and on the drawing, ,of which l though such a spring is not essential asl the,l

Figure l1 indicates a portion of the `mecha-Lk lever may be allowed to descend into locking 2o nism of an automobile showingan embodiposition by gravity. I provide cam Vmeans ment of my invention applied thereto. to move the lever out of, locking position 7i Figure 2 is, a. section on the line 22 of against the force of gravity and the springL Figure1. y j p 24.* This unlocking `means comprises a ver- Figure 3 is an elevation partly in section tically disposed shaft 25` on the lower end of another embodiment of myA invention, y of which is fixed a disk or plate 26, the plane Figure 4 is a plan view of a; portion of .of which is `inclined `to the axis of theishaft the a paratus shown inFigure V- 25. Anedge of the'disk 26 engages yunder n vRe erring to the drawing in detail, theauaV lug 27 formed on the lever 22. It isobvi-` vtomobile mechanism -illust-ratedin Figure 1 ous that rotation ofthe shaft 25 willjbring :eo is of a conventional type common to many; thehigh side of the disk 26 Vvunder thelug makesof cars and includes a main shaft 10` 27, thus raisingcthe lever 22 and unlocking from the motor, a clutch mechanism gen the transmission mechanism. At the uppererally indicated at 11, and transmission end ofthe shaft 25 is fixed a cylinder or lock- Vmechanismindicated at1 '2,which may be of barrelv 28 which is` provided vwith suitable',

any Ldesired' construction.` As shown the plungers and springs as foundin locking detransmission gears are shifted by a pair. of vicesv well known 'in the' art. The cylinder 28 g5 I Y shifter rods 13, 14 which are selectively en@ Vis journaled in the upper end of a column 29 gaged byca suitable knob 15 at the lower end which contains plungers 30 cooperating With of Van operating lever 16, this construction those in the cylinder 28 and locking the cylbeing well known in the art. In order to locky inyder 28 against rotation unless the proper: the transmissionmechanism in any desired key 31 is inserted. In Figure 3 this .form 90 position, neutral, reverse, or any speed foi-7 of my mechanism is illustrated in locked poward, I form a pair of notches k17 18 in the sition. In order to stop themotor when Lthe shifter rod 13 `and corresponding notches 19, transmission mechanism'isflocked, I y mount 45 2() in the shifter rod 14.k As shown in Figure. a'contact member 32 upon' the shaft 25 to V V4, the shifter rods are in neutral position turn therewith. On either side ofthe path 95 and the notches `17 18are respectively oppoof the contact member 32, I place* contacty site the notches `19, 20. The recess formed points 33, which pointsjare preferably con-J by the opposing notches 1.8, 20 is adapted lto nected into the ,ignitionicircuit The points l, serrbedto lock the transmission gear m any i. 33-ar`e so arranged with relation'to the con` tact member 32 that when the shaft 25 is rotated to a, position to lock the transmission,

` the Contact memberwill be separeted'rfrom Vthe, points 33, but when the shaftis rotated to unlock the transmission gears, the member Y 32 Will bridge the .gap between the points 33 and close that `portion of the ignition circuit.

VAs an additional safeguard, I provide e `look cuit.
